Abstract (en)
[origin: WO9728539A1] Radioactively contaminated material is cleaned by placing the material in a permeable container, such as a bag, and inserting the container into an apertured, rotatable vessel. The material is then subjected within the rotating vessel to a leaching cycle, using nitric acid, and a washing cycle, using fresh water. Preferably, at least one further washing cycle is employed. After discharging the washing liquid, the material is subjected to a spin-drying operation. The material undergoing cleaning is a filter medium which includes a glass component.
